QUESTION ABOUT JOSH PECK'S CHARACTER (spoilers)
Okay so this movie sucks and doesn't really make much sense, but there is something I have to ask to see if anyone has any plausible explanations.
Josh Peck's character Corey lied at least once, and probably twice.
The probable lie: he says his ATM card's magnetic strip is broken, which is why he couldn't access his account from the ATM. But eventually the other two characters ask him how he was able to enter the ATM building at all if his card doesn't work (since you need a card to open the door). This is a specific plot point that is brought up but never really resolved. The other guy hopes that Corey was just being cheap and lying about his card not being able to work because he didn't want to give out his money to the killer, but Corey just says "No...no" and then it's never brought up again.
The definite lie: early in the film the characters see the emergency fire sprinkler in the building and figure setting it off will alert the cops to come, and the girl specifically asks Corey for his lighter but Corey says he doesn't have one. But later, when the building is filling up with water, the other two find Corey's cigarettes and lighter in his jacket, which they use to start a fire and turn the sprinkler on.
So why did Corey lie?? I could buy him truly not understanding why his ATM card was being weird, letting him into the building but not letting him use the actual ATM. Or maybe he was just lying and being cheap, not wanting to give his money to the killer. With either of those scenarios though, it does just seem like sloppy filmmaking to bring up this plot point just to have it promptly forgotten and never brought up again or resolved.
But WHY lie about the lighter? I was sure they were setting up Corey to be in cahoots with the killer in some way, but no, Corey dies and there's nothing in the ending to suggest that he wasn't completely innocent. So why wouldn't he offer up his lighter early in the film to help set off the sprinkler??
You could say he was drunk and forgot he had a lighter on him, but that's a pretty *beep* explanation, he wasn't really that drunk, and again it feels like sloppy filmmaking for his character to specifically be asked for his lighter, claim he doesn't have one, then later on its discovered that he did have a lighter, without giving us any idea of why he would have lied about it.
